From 1 July 2025, the UK’s childhood immunisation schedule has undergone several important updates. These changes reflect the latest advice and are designed to better safeguard children against serious illnesses. One of the most notable additions is the introduction of the chickenpox (varicella) vaccine, which will be available free on the NHS from January 2026.
Here’s a simple breakdown of what’s changing and why it matters.
Chickenpox vaccine added to NHS programme
Starting January 2026, eligible children will receive a combined MMRV vaccine (measles, mumps, rubella, and varicella) as part of their routine immunisations.
This vaccine has been used safely for decades in countries like the US and Australia. It helps prevent chickenpox and its complications, such as bacterial infections, pneumonia, and even stroke.
Why it matters: Chickenpox can cause serious illness and lead to missing school and work for families.
Earlier protection against Meningococcal B (MenB)
The second dose of MenB will now be given at 12 weeks instead of 16.
Why it matters: Young infants are most vulnerable to illnesses caused by the Meningococcal bacteria (MenB), so earlier vaccination offers better protection during this critical period.
Hib/MenC vaccine removed at 12 months
Children born on or after 1 July 2024 will no longer receive the Hib/MenC (Menitorix®) vaccine at 12 months.
Why it matters: High coverage in adolescents means that infants are already well protected indirectly. There are alternative Meningitis C vaccines available for infants if required, but will not be offered on the NHS schedule.
New 18-month appointment introduced
From January 2026, children will be invited for a new 18-month vaccination appointment, which includes:
- a booster dose of the hexavalent vaccine (protects against diphtheria, tetanus, pertussis, polio, Hib, and hepatitis B)
- the second dose of the MMR vaccine
Why it matters: This change improves uptake and ensures children are protected before starting nursery or school.

Final thoughts from Dr Ioannou
“These updates reflect the UK’s commitment to keeping children safe through timely and effective immunisation. The addition of the chickenpox vaccine is a major step forward, and the revised schedule ensures better protection with fewer appointments. If you have questions, speak to your GP or health visitor - they’re here to help.”
